Notocacteae
Notocacteae is a tribe of cactus, cacti belonging to the subfamily Cactoideae. It is one of the oldest cactus lineages endemic to South America. Description Notocacteae are mostly single, rarely tree-like or shrub-like plants. Their mostly spherical, non-articulated shoots are ribbed, ribbed-warty or warty. The small to medium-sized, polysymmetrical to disymmetrical flowers open during the day. Their pericarpel has small scales. The areoles bear bristles or hairs. The fruits that burst or do not burst are usually dry and rarely berry-like. The small to medium-sized seeds are diverse in shape. The hilum and micropyle of the seeds are fused together, a strophiole is often present, and a slimy coating is sometimes present.

Cactoideae
The Cactoideae are the largest subfamily of the cactus family, Cactaceae, and are widely distributed throughout the Americas. Cactaceae is the 5th most endangered plant or animal family evaluated globally by the International Union for Conservation of Nature. Around 80% of cactus species belong to this subfamily. The genera of the Cactoideae are characterized by microscopic foliage leaves. All photosynthesis occurs in shoot cortex cells covered by a persistent epidermis and stomata. Another important characteristic of this subfamily is ribbed stems, which enable the inner cortex to expand radially without breaking the shoot surface to absorb large quantities of water.Mauseth, J. D. (2006). Structure–function relationships in highly modified shoots of Cactaceae. ''Annals of Botany, 98''(5), 901-926. , the internal classification of the family Cactaceae remained uncertain and subject to change. A classification incorporating many of the insights from the molecular studies was pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
